According to the present invention, an information processing apparatus comprises a first controller that executes a first program code; a second controller that executes a second program code different from the first program code, and communication with the first controller; a storage device that stores the first program code to be executed by the first controller and the second program code to be executed by the second controller; and a verifier that verifies, before the first controller and the second controller execute respective program codes, the respective program codes, stored in the storage device.

Information processing apparatus and method for controlling the same

There is provided a communication apparatus to which a telephone is connectable. While the telephone is disconnected from a telephone line, the communication apparatus shifts to a power saving mode. If an incoming call is detected in the power saving mode, the communication apparatus is returned from the power saving mode, and then controls to switch connection between the telephone and the telephone line in accordance with preset setting of an operation at the time of an incoming call.

Communication apparatus, method of controlling the same, and storage medium

An image forming apparatus equipped with a sleep function and for forming an image using an image forming unit and a control method thereof. The image forming apparatus includes a control unit that controls the image forming unit. When a job is received in a sleep state, a port number of the received job is discriminated, whether or not to perform initialization processing of the image forming unit is determined based on the discriminated port number, and in a case that it is determined that initialization processing of the image forming unit is necessary, initialization processing of the image forming unit is started and thereafter the control unit is controlled to start processing of the job.

Image forming apparatus with controlled activation based on port number and control method thereof

An image forming apparatus capable of communicating with a server apparatus, includes a receiving unit configured to receive a packet from the server apparatus, a determining unit configured to determine whether a packet received by the receiving unit is a specific packet, a power supply control unit which, when the determining unit determines that a packet received by the receiving unit is the specific packet, brings the image forming apparatus into a first power condition which enables the image forming apparatus to start quickly using data stored in a volatile memory, and a start control unit configured to start the image forming apparatus quickly using data stored in the volatile memory.

Image forming apparatus, control method of image forming apparatus and storage medium

The invention relates to an information processing apparatus which performs mirroring for synchronizing storage contents of a first storage unit and a second storage unit. If mirroring is valid when the information processing apparatus is started, the information processing apparatus detects a storage unit attached to itself. If a detection result indicates that no storage unit has been detected or one storage unit has been detected, the information processing apparatus displays, on a display unit, a connection acknowledgement screen for the storage unit which has not been detected. If the detection result indicates that two storage units have been detected, activation processing is executed for the information processing apparatus.

Information processing apparatus, control method therefor and storage medium

An image forming apparatus includes a communication unit configured to communicate with a server apparatus, a power supply control unit configured to repeat power supply to the communication unit, and an inquiry unit configured to make an inquiry to the server apparatus about whether to turn on a second power supply unit that energizes a controller that controls the image forming apparatus, each time the communication unit becomes communicable with the server apparatus by the power supply control unit, wherein the power supply control unit repeats power supply to the communication unit for each of a plurality of predetermined time periods, until receiving a response to turn on the power of the second power supply unit from the server apparatus in response to the inquiry by the inquiry unit.

Image forming apparatus, control method for image forming apparatus, and storage medium for performing power-saving control

This invention provides an image forming apparatus which performs sleep control for a shift to the sleep mode for each function and provides a user-friendly operation system, and a method of controlling the same. To accomplish this, the image forming apparatus sets a shift time until a power state of the image forming apparatus shifts to the low-power state after execution of image formation; and performs control to shift the power state of the image forming apparatus to the low-power state, when the shift time is not more than the predetermined time, before an elapse of the shift time after execution of image formation by the printing function, while shifting the power state of the image forming apparatus to the low-power state, in response to an elapse of the shift time after execution of image formation by the copying function.

Image forming apparatus, method of controlling the same, and program

An image forming apparatus according to the present invention is capable of connecting a removable storage device that stores operation data controlling an operation of the image forming apparatus. When a shutdown instruction of the image forming apparatus is received from a user, it is determined whether or not it is necessary to execute an operation using the operation data stored in the removable storage device. In a case that it is determined that it is necessary to execute an operation using the operation data, the image forming apparatus stores the operation data stored in the removable storage device into an incorporated non-volatile storage unit and shots down, and then restart. After the restart is performed, it is controlled so that an operation using the operation data that has been stored in the incorporated non-volatile storage unit is executed.

Image forming apparatus and method of controlling the apparatus

Raster image data is converted into block vector image data corresponding to blocks each having a predetermined size by segmenting the raster image data into the blocks with the predetermined size and executing vectorization processing. The input raster image data is converted into a block vector image. The converted block vector image is stored in a storage means. Transfer of the image data as a processing target in the apparatus is controlled to output the raster image data obtained by rasterizing the stored block vector image data.teh

Image processing apparatus, control method thereof, and storage medium storing a program for converting raster image data into block vector image format

An image forming system to which an external apparatus is connected and which accepts a plurality of jobs includes a display device for displaying information relating to the plurality of jobs, a device for changing a form of execution of the plurality of jobs displayed on the display device, and a device for changing a form of display of the information relating to the plurality of jobs so as to be able to identify the change in the execution form.

Image forming system that renews starting times of interrupted jobs

An image processing apparatus for controlling an execution order of a plurality of processing operations comprises an input device for inputting a plurality of jobs for image processing, a storage device for storing the plurality of jobs input by the input device and a controller for sorting an execution order of the plurality of jobs stored in the storage device in accordance with times required for processing of each of the jobs, and further sorting the execution order of the plurality of sorted jobs in accordance with whether each of the jobs corresponds to an image input or an image output, wherein the controller executes each of the jobs according to the execution order of the plurality of sorted job.

Image processing apparatus with multiple functions

Image retrieving and storing processes by a mark sheet are facilitated. It is determined whether or not a mark sheet is directed in a correct direction by determining the positional relation between a direction discriminating mark and mark sheet identifying marks. If the mark sheet is directed in a wrong direction, the direction of the mark sheet is corrected. If it is determined in a primary retrieval operation that there are a plurality of candidate images, a mark sheet for a second retrieving operation is output.
